RADIATOR.

SPECIFICATION forming part of Letters Patent No. 437,680, dated October'7, 1890.

Application filed September 12, 1889- Serial No. 323,783. (No model.)

To (ZZZ whom, it may concern:

Be it known that I, HARRY A. ORossLnY, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Radiators, of which thefollowing is a specification.

This invention relates to steam-heating radiators, and has for itsobject to cheapen and facilitate the construction of tubular radiators;and it consists in the peculiar construction and combination of theparts comprising the radiator, substantially as hereinafter described,and pointed out in the claim.

In the accompanying drawings, Figure 1 is a side elevation of aradiator, partly in section, having a double base and showing myimproved means of constructing and joining the circulating-pipes withthe bases. Fig. 2 is an end elevation of the same. Fig. 3 is a sectionalView of part of a single base and a few circulating-pipes, on anenlarged scale, showing the construction and application of hollowperforated clamp bolts or plugs for securing the circulating-pipes tothe bases. Fig. 4 is a cross-sectional View of a double base and a groupof circulating-pipes, showing my new means of uniting the pipes to thebases.

A represents bases or base-pipes for carrying circulating-pipes, as B orB The bases are provided on their top sides with a row of holes havingcountersunk holes for receiving the ends of said circulating-pipes. Thebases are also provided on their under sides with a corresponding row ofholes directly opposite the top row. The bases are also divided bypartitions a at, extending nearly to the bottom, dividing the interiorinto spaces, having two of said holes between each partition, except atthe ends.

B represents circulating-pipes, which may be joined in pairs at theirtop ends by elbows, as b b, or they may be made in groups, as seen inFig. 4:, and have two general bottoms, as B with necks, as 11 forattachment to the bases, as represented. The inside of the lower openends of the circulating-pipes B and the necks b are screw-threaded.

O 0 represent hollow clamping bolts or plugs designed for securing thepipes B to the bases A. Their open ends are screw-threaded on theoutside for screwing into the ends of the pipes B. Their closed endshave flanges, and their sides are perforated to allow steam to circulateinto and through them. By the use of these hollow bolts or plugs thesecuring of the circulating-pipes to the bases is very readily, easily,and quickly done.

The circulating-pipes are set into the countersunk holes in the bases inpairs or in groups, with a suitable gasket or packingring, and the boltsare inserted through the opposite holes and then tightly screwed up.

into the ends of the pipes B, firmly uniting them to the bases, a gasketwith the flange on the end of bolts closing the lower holes. These arereadily removed for repairs or other purposes.

What I claim, and desire to secure by Letters Patent, is

The combination, with the bases of radiators, as A, having a row ofcountersunk holes in their top sides and a corresponding row of holes intheir under or opposite sides, and thecirculating'pipes, as B B,interiorly threaded, of the hollow and perforated clamping bolts orplugs O G, exteriorly threaded, substantially as and for the purposespecified.
